Link roundup before rebooting

The time has come for an OS upgrade to OSX 10.5.6, and as Firefox 3.1 beta 2 has kept up very well for a long time, I now have a huge number of tabs open. So here are some worth reporting on here, the rest are on my delicious feed.

I started looking into cloud computing and the semantic web and found a few really nice links:

Bigdata(R) is an open-source scale-out storage and computing fabric supporting optional transactions, very high concurrency, and very high aggregate IO rates. Bigdata was designed from the ground up as a distributed database architecture optimized for very high aggregate IO rates running over clusters of 100s to 1000s of machines, but can also run in a single-server mode. Bigdata offers a distributed file system, similar to the Google File System but also useful for workflow queues, a data extensible sparse row store, similar to Googles widely recognized bigtable project, and map/reduce processing for parallelizing data intensive workflows over a cluster.

Bigdata(R) comes packaged with a very high-performance RDF store supporting RDF(S) and OWL Lite inference.[...]The Bigdata RDF Store was designed specifically to meet requirements for very large scale semantic alignment and federation.

An very nice web2.0 demo by deeda of an interface on social networks, people's location and how one can buy them some presents. Clearly they need distributed social networks if they are not just to become another facebook app.
